If you choose to connect with us through a social media platform, we may, through the social media platform connection, collect additional information from you, such as your user names, profile picture, contact information, contact list, and the profile pictures of your contacts. Similarly, the social media platforms may collect information about your interaction with our Products and Services. We do not have any control of the collection, use and sharing of your information when using any social media platforms. You should read any associated privacy policies before using them.
Information we collect from other sources, e.g.: information from third party providers, information that helps us to combat fraud or that relates to your social interactions (including your communications via social media, between individuals, organisations, prospects and other stakeholders acquired from companies that collect combined information);
We may combine the information we collect about you from the various sources described above.
WHY WE COLLECT YOUR INFORMATION (PURPOSES)
This section explains why we collect your information and what we need it for (purposes). This is set out below, by reference to what the information is required for.
We collect and process your personal information in order to offer the Network, and to offer you our Products and Services.
If you decline to provide us with personal information when we ask you, you may not be able to access all or some of our services and you may not be able to use the Network or certain Products and Services. For example, if you do not provide us with your email address or other information required for account registration, we will not be able to register you for certain account services.
Account registration information
We need to collect your personal information for account registration purposes. Although the Network provides for anonymous and pseudonymous participation, in some instances in order to use certain Products or Services, we require account registration. This requires a name associated with your account, an email address at which we can contact you, and in some cases, additional information including, a contact address, a billing address, and a password to help secure your personal information.
When completing a public “profile”, whether it is for use with the Network or our Products and Services, we may require you to share certain personally identifying information in required and optional profile fields. The name associated with your account, which you may review and change in your account settings, as well as reputation points are publicly displayed and connected to your activity on the Stack Overflow Network and via certain Products and Services such as our Talent and Teams platforms.
Similarly, you may elect to share additional information that is not required but this will be displayed publicly at your election.
If you are using the private Network (e.g., Stack Overflow for Teams), your account settings including, name, affiliated role and company, and other information may be shared with your private Network Team members designated as authorized users of your private Network account. While some of the public and private Network profile information is required, much of it is within your control as we describe herein and can be modified, updated, and restricted by you in your Profile Settings.
Information we use to identify and authenticate you. We need this information to be able to recognize you, for example, when you access your accounts. It also helps us to protect your details and keep them secure.
Device and browser information received automatically
When you visit the Network or use our Apps, Stack Overflow automatically receives and records information from your browser or mobile device, such as your Internet Protocol (IP) address or unique device identifier. Cookies and data about which pages you visit on our Network allow us to operate and optimize the Products and Services we provide to you. This information is stored in secure logs and is collected automatically.
We may combine this browser information with other information we collect about you. This information is used to keep the Products and Services secure, to analyze and understand how our Products and Services are used, optimize such usage, provide advertising across the Network as well as certain Products and Services to personalize your experience, and to help connect you with potential job opportunities in the case of our recruiting Products and Services.
When you use the Stack Overflow Network, and certain of our Products and Services, we collect location information about you including your IP address, your location, browser information, and how you came to the Stack Overflow Network. This is the case for individuals who have registered for an account, and non-members who engage with the Stack Overflow Network by visiting our website(s) but who have not completed an account registration.
This information is collected for various purposes, including advertising, analytics and to serve content as it relates to certain Products or Services (e.g., Talent), as well as to provide you with localized content, recommendations, and marketing. You may revoke our permission to collect some of this data, including your location and browser information through your Account Settings, but this may limit functionality in some cases. Certain location information we collect is required for security and site functionality. We share this information with certain third-parties (e.g., talent recruiters, payment processors, and advertising providers) in order to provide you with our Products and Services.
WHO WE SHARE YOUR INFORMATION WITH
Advertising and marketing partners
Stack Overflow uses data analytics to ensure site functionality and to optimize our Product and Service offerings to you. We use web browser and mobile analytics to allow us to understand Network and Apps functionality. In doing so, we record information including, for example how often you visit the Network, how often you contribute content, Network and Apps performance data, errors and debugging information, and the type of activity you engage in while on the Network or in your use of our Products and Services. We may on occasion share this information with third parties for research or product and services optimization.
For Products and Services requiring payment, we collect a billing name, phone number, and email address. We also collect a billing and shipping address for invoicing purposes. If you elect to pay by credit card, Stack Overflow may engage a third party to securely process your payment. All payment processing is done through a PCI DSS compliant third party. If customers are paying by a credit card, their card details are vaulted through a third-party payment gateway. Stack Overflow will store an encrypted token along with the last four digits of the credit card and the expiration month and year of the card and will not store or retain any other billing information about you.
As the world’s largest developer community, Stack Overflow publishes an annual Developer Survey to provide key insights into the developer community, as well as other surveys from time to time, all of which include demographic (e.g. gender, race, age etc) and certain personal information. Your participation in the Developer Survey as well as any other Stack Overflow survey is entirely voluntary. In order to provide meaningful insights into the developer community, Stack Overflow may collect sensitive data about you, including, but not limited to your gender, race, sexual orientation, immigration status, and your location. We consider this data to be among our most sensitive, and have taken elevated measures to protect such data as well as to de-identify your name and other personal information from such data. We restrict such data within Stack Overflow on a privileged basis to only those that need to see it and while we may share your personal information with certain third parties such as researchers, we do so only after imposing contractual obligations of confidentiality on such third parties and only where absolutely necessary for limited research purposes.
When we publish our surveys, they are published as a compilation of anonymized data, which means that we take every effort to ensure that your information is understood in a statistical narrative decoupled from your personal identity.
If you have any questions concerning the Developer Survey or other survey and our security measures to protect your sensitive personal data, please contact us at: privacy (at) stackoverflow (dot) com.
Legal basis for processing your information
We will only use your information where we have a legal basis for using it, for example, where we have your consent, or where we need to carry out processing to provide you with a service you have requested. This section describes the legal bases we rely on for processing your information, including when we share it with third parties.
When you access the Stack Overflow Network and use the Products and Services we offer, we collect, display, store, share, transmit, and process your information in the manner described in this policy.
In order to carry out these activities, Stack Overflow may rely on the following legal bases in order to process your personal data:
- Where you have given us consent to process the information, which you can withdraw at any time.
Where the processing is necessary:
- to carry out the contractual obligations in the Terms of Service or to provide the Products and Services you have requested
- to comply with a legal obligation or to defend legal claims
- to protect the public interest or vital interest of others
- Where it is in our legitimate interests, or that of a third party to carry out the processing.
Whenever we rely on legitimate interests for processing, we ensure that we consider and balance our interests against the individual’s interests before processing. We do not use your personal data on the basis of legitimate interest for activities where individuals’ interests override our interests.
Where we process your information on the basis of legitimate interests, we do so in order to:
Secure your personal data and information
Stack Overflow is committed to the safety and security of your personal data and the information that you share with us and with the public. We treat your personal data and safety from harassment as top organizational priorities. At Stack Overflow we consider it necessary to pursue these legitimate interests in order to keep our community, you and your information safe from spam, harassment, intellectual property infringement, identity theft, and the scraping and unlawful collection of your information.
Provide and optimize products and services
We use your information to provide and improve our Products and Services, for identification, verification, to provide support, for online and offline marketing including through third party tools such as Google Analytics, and for general research and analytics reporting. In doing so, we may learn which of our Products and Services you are using most, what you’re interested in, and to better enable you to use and access our Products and Services. As a core part of our business, Stack Overflow has a legitimate interest in enabling and customizing your experience of our Product and Services offerings.
Engage in commercial transactions
As part of providing our core Products and Services, Stack Overflow may charge you for the use of some Products and Services, or certain features within these Products and Services. In order to process your payment, and to secure your financial information, we may facilitate the sharing of your information with third parties. We share your information only with third parties who have met strict security standards and consider the secure processing of your financial information to be a strict and legitimate business necessity.
Comply with regulatory and legal obligations
Stack Overflow has a legitimate interest in complying with certain legal obligations and interests which, from time to time, may require the disclosure of your personal information. Stack Overflow will not disclose your personal information to legal authorities except where such disclosure is by lawful request, including to meet legitimate national security or law enforcement demands (including a subpoena, court order, or other lawful legal demand by a legal authority with lawful jurisdiction). In some cases, we may also release your personal information to defend our legitimate legal interests. We consider our obligation to protect the Stack Overflow community from imminent physical harm to be both a legitimate business interest as well as to be within the public interest and may disclose your personal information if we believe you or another individual may be in imminent danger of harm to yourself or to another.
Marketing and product communications
From time to time, Stack Overflow may communicate with you about commercial and other Product and Services offerings. In doing so, we provide you with an opportunity to opt-out of such messages at any time you choose via your account settings. Stack Overflow will not sell your personal information to enhance our marketing opportunities or profitability (except as may relate to a corporate event such as a sale or merger), and as we are committed to preventing spam, our direct marketing efforts are limited in scope and frequency. We engage in such activities as a legitimate business interest in order to promote key Products and Service offerings and provide you with every opportunity to unsubscribe from such communications or to further limit their scope and frequency. In short, while we want to communicate some key commercial communications with you and have determined it to be a legitimate interest for us to be able to do so, you have the final say in whether or not you would like to receive such commercial communications from us. You can review or change your permissions in your Profile Settings.
Core business operations
Stack Overflow may engage with third parties in business transactions including the buying and selling of assets, the auditing of our business practices and financials, and to engage in business development opportunities. These core activities may involve the processing and/or disclosure of some limited personal information which may be necessary and within our legitimate interests to develop the Stack Overflow brand and business. If we transfer any personal information in pursuing such a business transaction, we will always ensure that strict confidentiality measures are in place to protect your privacy interests.
YOUR CHOICE AND CONTROL OF THE INFORMATION WE COLLECT ON YOU
Privacy is a guiding principle of all Stack Overflow Products and Services and we value your privacy. To this end, we provide you with the ability to control how your information is stored, and what information is collected. You may change or correct your account settings and choose not to share certain information by creating a pseudonymous account. Additionally, much of the data we collect is voluntary and your choice entirely to provide us or not. You may also remove certain optional information that you no longer wish to be publicly displayed, such as your photo, or job history. In the event Stack Overflow decides to provide additional opt-out or opt-in mechanisms under the Privacy Shield Framework, the mechanisms will be clear, conspicuous, and readily available for you to exercise your choice. And of course, should you wish, you may also request the permanent deletion of your account, in which case all personal information collected on you will be removed from our servers and encrypted (except, in some cases your IP address required for security purposes, site maintenance, and spam protection).
We also provide you additional data control options created by the GDPR, but provided to the Stack Overflow community regardless of geographic location with respect to your information, including data access and portability (including the right to obtain and download a copy of the personal data you provided to Stack Overflow), data correction (the ability to update the personal data we collect and display on you, in many cases via your account settings), data deletion (where Stack Overflow will delete personal information stored on you, which we are not required by necessity to maintain), and the ability to have us stop processing your personal data (with certain exceptions as may be necessary). You may submit data requests to email@example.com.
Please also be aware that in order to respond to data requests and provide data choices to you, we may need to first verify your identity.
You may additionally control the receipt of certain marketing and advertising communications from Stack Overflow. Some messages that we send are required, and related to our legal obligations, or service related and mandatory. Other messages, like marketing and advertising communications are provided by us to let you know how you can continue to share, learn, and build your knowledge within the Stack Overflow community, and are voluntary. We provide you with the opportunity to control which voluntary (non-mandatory/required) messages you would like to receive in your Profile Settings.

INTERNATIONAL DATA TRANSFERS
Stack Overflow is a global community and as such, you may access the Stack Overflow Network from almost anywhere in the world. When you do this, you will also be subject to the local laws of your jurisdiction you are accessing it from. By accessing the Stack Overflow Network and engaging with our Products and Services, you acknowledge that your personal data may be collected and transferred from your local jurisdiction (including member states to the European Union) to the United States.
Where Stack Overflow transfers your personal data from your local jurisdiction (including member states to the European Union) we rely on certain lawful transfer mechanisms to do so, including the following lawful bases for such transfers:
Standard contractual clauses
The European Commission has adopted standard contractual clauses (also referred to as model clauses), which provide safeguards to protect the transfer of personal information outside of the European Union. We may use these standard contractual clauses when transferring personal information outside of the European Union. You may review and request a copy of such standard contractual clauses as used by Stack Overflow by contacting us at legal (at) stackoverflow (dot) com.
OUR ONGOING COMMITMENT TO DATA SECURITY
Security is important to us and we know it is important to you. Stack Overflow follows generally accepted standards to protect your personal information when processing, transferring, and storing your personal information including Transport Layer Security (“TLS”), by restricting your personal data when we do not need to access it and by keeping your personal data only as necessary to perform our legitimate business interests.
As the data subject, you too have an important role to play in helping us protect your personal information. We encourage you to protect yourself against unauthorized access to your personal information by choosing a password carefully and in accordance with industry best standards. Do not share your password with anyone you do not trust, and make sure your computer accesses Stack Overflow via a secure network and that you do not leave your personal information vulnerable to hackers and other bad actors by leaving your computer unattended or by failing to logout of your account when you have ended your session activity.
DIRECT MARKETING OPT OUT
You may opt-out of receiving Stack Overflow email marketing materials by using the unsubscribe link in these communications or by changing your Email Settings.
